Answer:
(attached file #2)
Explanation:
let's change the variable n to a variable x (it can be x and y):
x ≥ -8
go to the X-axis which is the line going horizontal, just as the first picture attached!
2. Now go to the -8 on that line and draw a straight bold line going up (vertical)
and there you have the answer to the question.
if the question was with this symbol: < or > then the line would be dashed instead of being a bold solid straight line!
Hope this helps,
